Which button is clicked?

Anonymous — Thu, 01 May 2014 06:29:08 GMT

The addin I am writing adds a ribbon panel with two buttons (button A and button B) to the "Add-Ins Ribbon".

Clicking these buttons will both execute the "Public Function Execute(commandData As Autodesk.Revit.UI.ExternalCommandData, ByRef message As String, elements As Autodesk.Revit.DB.ElementSet) As Autodesk.Revit.UI.Result Implements Autodesk.Revit.UI.IExternalCommand.Execute"

I would like to know which button is being clicked (A or B).

How can I determine this?

P.s. In my .addin manifest, I have defined only one "Command", so under the "External Tools", only one command show up (as expected).

To my knowlege this info isn't passed on by the API. There are ways around it though as discussed in this post from a couple years back: http://forums.autodesk.com/t5/Revit-API/Which-pushbutton-caused-the-ExternalCommand/m-p/3698908

Is there a reason that you can't just have a separate command for each button?

Having a separate command for each button is no problem...

...except that I don't even know how my current buttons are currently "linked" by the ".addin manifest" to the "Execute command".

The way my addin looks right now: a panel with two buttons on the Addin Ribbon and one command under the "External Tools"...but they are ALL connected to one and the same Execute command.

I hope you understand what I am trying to say. Maybe you can show me an example of having multiple commands (linked to different buttons)?

I typically create an Addin Application and then have all command buttons created and associated to the commands during the OnStartup method of the addin. I have linked an example visual studio 2010 solution set up for Revit 2014, it's very bare bones but take a look to see how it's done.

Right! That example makes perfect sense. I was writing all the code in one class, you wrote a class for each button/command.

The only thing missing in your example is the ".addin manifest", but I bet I can recreate it.

Thanks a ton for sharing that example!

No worries glad to help.

BTW I did include a manifest in the zip file it is called RibbonExample.addin

Dear Teun Ham,

This question has actually been discussed a couple of times in the past, so I added an explanation of it to The Building Coder as well:

Aaah, I missed it completely. I guess I expected it was an ".suo" file (Visual Studio Solution User Option). I will pay better attention to the file extension next time 🙂
